Begin by rinsing the fresh strawberries under cold water, pat them dry gently, then slice the berries into quarters.

In a medium saucepan, combine the sliced strawberries, white sugar, fresh lemon juice, and vanilla extract. Stir gently to evenly coat the strawberries.

Place the saucepan over medium heat and bring the mixture to a gentle simmer. Cook for 5–7 minutes, stirring occasionally.

If you prefer a thicker topping, dissolve the cornstarch in water and stir it into the simmering fruit. Continue cooking for an additional 2 minutes.

Remove the saucepan from heat and let the topping cool for a few minutes before serving.
